Breaking concrete from the outside requires overcoming its compressive strength.If, however, it can be broken from within, its only necessary to overcome the tensile strength which is about 15 of the compressive strength.Dynamite is an option for imploding a building, but according to the national demolition association, implosions.
Absorbents are used in dynamite to hold the explosive base from exudation, seepage, and settle-ment to the bottom of the cartridge or container. Sawdust, rice hulls, nut shells, and wood meal are often used as absorbents. Antifreeze. Antifreeze is used to lower the freezing point of the explosive. Air gap sensitivity.

CONDITIONS CALLING FOR CONCRETE REMOVAL AND REPLACEMENT. There are certain conditions under which using a patching compound and resurfacing product will result in merely a short-term fix. Under these conditions, patching the concrete prior to resurfacing or doing a decorative topping would be a waste of time and money, as the surface or topping would soon
amount of explosives required to break a unit measure of rock. Since rock is usually measured in pounds, there are several possible combinations that can express the powder factor. Powder Factor = Tons of rock (or cubic yards) per pounds of explosive. Normal range = 4 to 7 Shallow holes = 1 to 2 External loads = .3 Tons of Rock = Powder Factor
Blasters use different explosives for different materials, and determine the amount of explosives needed based on the thickness of the material. For concrete columns, blasters use traditional dynamite or a similar explosive material. Dynamite is just absorbent stuffing soaked in a highly combustible chemical or mixture of chemicals.

The explosives 125 pounds of dynamite and the military explosive C4, plus 75 pounds of gunpowder were stolen between Saturday and Monday from a concrete bunker about 20 miles northeast of Fresno.
The split concrete is then easily removed, either by hand or by crane. Hydraulic pressure bursting break up concrete structures with a minimum of noise and flying debris. This method works by applying lateral forces against the inside of holes drilled into the concrete, and can do virtually any job other demolition methods are capable of.
The Micro-Blaster IIx3 will allow users to break much larger masses of rock or concrete than with just the single head models. Users will need to supply a source of compressed air or CO2 (minimum 75 psi, 7 gallon portable air tank recommended) to trigger their systems.

Dec 16, 2010· Secondary concrete crushers usually have some type of pulverizing jaws and are used on jobs where primary demolition is accomplished by hammers, crushers, blasting, ball and crane, or sawing. In this instance, the primary demolition work creates large quantities of concrete rubble which the secondary crusher further reduces, separating concrete
Detonating cord (also called detonation cord, detacord, det. cord, detcord, primer cord or sun cord) is a thin, flexible plastic tube usually filled with pentaerythritol tetranitrate (PETN, pentrite). With the PETN exploding at a rate of approximately 6400 m/s, any common length
The split concrete is then easily removed, either by hand or by crane. Hydraulic pressure bursting break up concrete structures with a minimum of noise and flying debris. This method works by applying lateral forces against the inside of holes drilled into the concrete, and can do virtually any job other demolition methods are capable of.
Concrete aggregate collected from demolition sites is put through a crushing machine. Crushing facilities accept only uncontaminated concrete, which must be free of trash, wood, paper and other such materials. Metals such as rebar are accepted, since they can be removed with magnets and other sorting devices and melted down for recycling elsewhere.
